When Superman was infected with a form of
Kryptonite spawned cancer, other members of
Strike Force Superman with the aid of Dr.
Hamilton were able to extract the organism.

Months later Superman followed a rash of mass killings by an adversary capable of stripping the flesh from
its victims. When he tracked the monster down it called him "father" and attempted to kill the Man of Steel,
who suffered a tremendous beating at the tentacles of Kancer.
